Titanic's sister ship, the Olympic, is damaged again. Mark can't leave. Sofia also has to postpone her plans. Pietro has been injured at work and she must look after him. Mark and Andrews look for new solutions. The gashes in Olympic suggest that the steel is just too weak. Eventually they have to concede that the steel, combined with the sheer scope, is just not good enough. The double hull would have protected the ship - Perhaps the bulkheads too. For this to become a serious problem, Titanic would have to crash into something very solid. An occurrence that seems remote on the Atlantic Ocean. While Mark and Andrews slowly come to their conclusions, Emily is sentenced to an astoundingly unfair six months in jail. But another terrible event occurs: Conor is shot dead while the Unionists start advocating a new, separate State, Northern Ireland.

That producers opt to tell a different Titanic story is admirable in light of so many filmed versions of the story that already exist, including a four-hour miniseries that aired on ABC earlier this year. But the decision not to reveal the fates of the miniseries' fictional characters may feel like a cheat to anyone who invests 12 hours in this program.
